`proved i'ioat provided with means wherebyit can be propelled-through the Water and directed in its movements. A

The object of the invention is to design'l an improved float of this cliaractei'- which is simple and inexpensive in its construction and can be-readiiy collapsed when not in use so as to occupy a comparatively small amount of'spac'e. 4 l For a full description of the invention and the merits thereof and also to acquire la knowledge of the details of construction and the means for effecting the result, reference is to be had to the following description and accompanyii'igl drawings, in whichz.

Figurcl is a top plan view of a float device constructed in accordance with the invention. Fig'. 2 is aside elevation of these-me. Fig. 3 is a longitudinal sectional view through the same. Fig. 4 is a top plan view of the rear end of the device, the buoyant member being removed. Fig. 5 is a transverse sectional view through the device.

Corresponding and like parts are referred to in the following' description and indicated in 'all the views of the.drawingsA bythe same reference characters. I

The float comprises an elongated frame 1 provided at its opposite ends with buoyant members by means of which it is supported a in the waterfand in thepresent instance this frame 1 is collapsible to admit of the device being folded when not in use. `In the specific 5o the sections of each side piece of the frame is .formedwith a loi'igitudinal slot 2V loosely re-` ceiving a threaded stud 3 projecting from tlie opposite section, the said stud being provided with a clamping nut 4 which isradapted when 5 5 tightened to lock the sections against sliding,`

constructionof thc frame it will be observed that the saine is formed with spaced longi' novenientl lt will also be observed that the slotted section of each side piece has asleeve slidably mounted thereon, the said sleeve being designed to engage -the end of the opposite section to prevent pivotal movement thereof' and beingr provided with a set screw 6 by means of which it can be locked against accidental displacement. 'With this construction it will be obvious that by loosening the nuts 4 the side ieces can be shortened or elongated a's"`requiied,and that when the sleeve 5 is moved into an inoperative position the sections of the side -pieces can beswung against each other. As previously mentioned this frame is supported in* the Water by buoyant members or floats, a iioat 7 being located at the rear end "of the frame anda second float 8 at the forward end of the frame, AFor the purpose of moving the float through the water in a positive manner a propeller 9 is utilized, the said propeller being rigid with a longitudinal shaft l() provided at its forward extremity. with a pinion 1,1 meshing'with teeth upon 'the periphery of a drive wheel 12. This drivenvheel oper- -ates within a recessed vportion of the rear iioat 7 and is jour-naled upon a v,suitable bracket 13. A crank 14 rigid with the drive wheel 1.2 is located upon each side thereof, and the said cranks are connected by means of the links 15'to foot levers-1G pivotally' 'mounted upon odset portions of a. transverse bar 17.

A rudder 18 is provided at the forward end of the v shaft 19journaled upon the frame and a fori ard cross bar 20. The rear end of thisshaft 19 is ext-ended upwardly and provided with a handle bar 21 by means of which' the rudder can be turned and the movements of the frame and is rigid with a longitudinal -iioat device directed inthe desired manner.

Specifically describing the rudder it will be observed that the. saine comprises a pair of rearwardly diverging sides and is pointed at its lower end, the upper end being rigidly connected to theshaft 19.v

A support for. the operator is provided between the front cross bar 420 and the rear cross bar 1 7 and in the present instance this support 22 is formed of fabric, one end of the fabric being` wrapped around the forward cross bar while' the opposite end is split or .bifuroated and secured to the end portions of the rear cross bar 17.

ln the operation-of the device the person lies uponthe support v22 and reciprocater'sthe l levers 16 with his f eet, the direction of I nove- .ofthe various people Who may use it. In

this connection ity may also be mentioned that the 'drive wheel 12 may beY made in any desired size so as to cause the propeller to rev 'folv'e at-'anyrequired relative speed.

. Having thus described the invention, what isclaimed as new is: l I ,1. The combination of a'frame comprising spaced side pieces formed insections having a pin and slot connection which admits of theirghaving both a sliding and pivotal movement with relation to each other, means for locking the sections rigidly together in alinement-.With each other, iioats for supporting 91eme the 'frame' and 4means for propelling the frame. I

2. The combination of a frame comprising spaced side pieces formed in sections, one of the sections of each side piece being slotted and the opposite section being provided with ya pin loosely received within lthe slot, Whereby the tWo sections have both a sliding and pivotal connection, a' sleeve for locking the Sections in alinement with each otherhiloats for supporting the frame, and'means for pro'- pelling the frame. l,

3. 'lhe combination of a frame, a float for supporting the frame, means for pro elling the frame, a horizontal shaft j ournale upon the frame, and a rudder carried bythe horizontal. shaft, the said rudder comprising a pairpf rearwardlyfdivergigng sides and servl ingto guide the frame in its movements.

In testimony whereof l aflix my signature in presence of two Witnesses. Y
